Authors present a rare case of upper digestive bleeding, the etiology of which is represented by a pancreatic papillary adenocarcinoma placed in the body and tail of the pancreas, with bleeding through the Oddi's sphincter, which causes difficult problems of medical and surgical diagnosis and treatment. The patient was known with acute cholecysto-pancreatitis of lithiasic cause, which has been surgically cured in 1977, being under treatment in the last years for the pancreatic injury which had been chronic pancreatitis and for hyperglycemia. The laboratory explorations emphasized a severe anaemia which was identified through upper digestive endoscopy (intermittent active bleeding from the major papilla) confirmed by echo and CT exam (heterogeneously body tissue of 10/8 cm diameter, involving the body and the tail of the pancreas). The medical treatment was complex, including proteic, hematologic, acido-basic, balance of hyperglycemia, and was followed by the surgical intervention consisting in body and tail pancreatico-splenectomy, followed by a postsurgical abscess, which required drainage. The surgical evolution was favorable. 6 months after leaving the hospital, the patient was admitted to medical diseases clinic with the diagnosis of deep right ileofemoral thrombophlebitis, duodenal acute ulcer and acute pneumonia of average right lobe, causing difficult problems of medical treatment. On this pathologic background, the diabetic failure also appears and the echo exam showing multiple secondary hepatic and peritoneal metastatic determinations. In medical literature we only met 13 similar communications, problems of diagnosis and treatment being very much alike to those presented.

Results of surgical treatment of 61 patients with injuries of the duodenum are analyzed. The causes of injuries were stab-incised wounds in 24 patients, missile wound -- in 7, closed abdominal trauma -- in 26, trauma of the duodenum during endoscopic papillosphincterotomy -- in 4. All the patients underwent surgery. Complications were seen in 32 (52.5%) patients, 21 patients died, lethality was 34.4%. Within the first 24 hours since the trauma 7 patients died due to severe combined trauma, blood loss, 54 patients survived acute period of trauma, including 28 patients after open trauma, 26 -- after closed and 4 -- after trauma of the duodenum during endoscopic papillosphincterotomy. Diagnostic and surgical policies are discussed. Results of treatment depending on kind and time of surgery are regarded. It is demonstrated that purulent complications due to retroperitoneal phlegmona, traumatic pancreatitis, pneumonia are the causes of significant number of unfavorable outcomes. Therefore, it is important to adequately incise and drainage infected parts of retroperitoneal fat tissue with two-lumen drainages. Decompression through duodenal tube is the effective procedure for prophylaxis of suture insufficiency and traumatic pancreatitis. Suppression of pancreatic and duodenal secretion with octreotid improves significantly surgical treatment results.

A 53-year-old woman was admitted with respiratory distress. For several years, she had chronic alcoholic pancreatitis with ductal stones that were treated with a stent and with shockwave lithotripsy. Both treatments were unsuccessful, and the pancreatitis was complicated with an infected pseudocyst. The pancreatic head had to be resected, which was complicated with recurrent subphrenic abscesses. She then was admitted with respiratory distress and initially diagnosed with pneumonia of the right lower lobe. Further investigations showed supradiaphragmatic and subdiaphragmatic air-fluid levels. In both collections Streptococcus milleri was cultured, and subsequently the patient was diagnosed with a fistula connecting the subdiaphragmatic abscess with pulmonary tissue. This was treated with intravenous amoxicillin/clavulanate and drainage of the subdiaphragmatic collection. She did not develop a pulmonary empyema, because multiple adhesions, which were due to recurrent abscesses after pancreatic surgery, prevented breakthrough into the pleural cavity.

Diabetic ketoacidosis (DKA) is the most common hyperglycemic emergency in patients with diabetes mellitus. DKA most often occurs in patients with type 1 diabetes, but patients with type 2 diabetes are susceptible to DKA under stressful conditions, such as trauma, surgery, or infections. DKA is reported to be responsible for more than 100 000 hospital admissions per year in the US, and accounts for 4-9% of all hospital discharge summaries among patients with diabetes. Treatment of patients with DKA uses significant healthcare resources and accounts for 1 out of every 4 healthcare dollars spent on direct medical care for adult patients with type 1 diabetes in the US. Recent studies using standardized written guidelines for therapy have demonstrated a mortality rate of less than 5%, with higher mortality rates observed in elderly patients and those with concomitant life-threatening illnesses. Worldwide, infection is the most common precipitating cause for DKA, occurring in 30-50% of cases. Urinary tract infection and pneumonia account for the majority of infections. Other precipitating causes are intercurrent illnesses (i.e., surgery, trauma, myocardial ischemia, pancreatitis), psychological stress, and non-compliance with insulin therapy. The triad of uncontrolled hyperglycemia, metabolic acidosis and increased total body ketone concentration characterizes DKA. These metabolic derangements result from the combination of absolute or relative insulin deficiency and increased levels of counter-regulatory hormones (glucagon, catecholamines, cortisol, and growth hormone). Successful treatment of DKA requires frequent monitoring of patients, correction of hypovolemia and hyperglycemia, replacement of electrolyte losses, and careful search for the precipitating cause. Since the majority of DKA cases occur in patients with a known history of diabetes, this acute metabolic complication should be largely preventable through early detection, and by the education of patients, healthcare professionals, and the general public. The frequency of hospitalizations for DKA has been reduced following diabetes education programs, improved follow-up care, and access to medical advice. Novel approaches to patient education incorporating a variety of healthcare beliefs and socioeconomic issues are critical to an effective prevention program.

Neospora caninum is a recently described apicomplexan parasite first isolated from a dog in 1988 and has subsequently been shown to infect a wide range of mammals. In mice, Neospora can cause primary pneumonia, myositis, encephalitis, radiculoneuritis, and pancreatitis. Whereas, certain aspects of the host immune response to Toxoplasma gondii have been well studied, not as much is known about the full immune response to Neospora. This paper examines whether or not immune splenocytes are able to adoptively transfer protection against N. caninum infection in BALB/c mice. Mice receiving immune enriched CD8+ cells had severe neurological signs by 19 days post infection. Mice receiving immune enriched CD4+ cells had mild neurological signs on day 22 post infection. It would appear that additional immune cells can precipitate disease in the presence of circulating lymphocytes.

The acute respiratory distress syndrome (ARDS) is a life-threatening syndrome that may occur in any patient without any predisposition and that is mostly triggered by underlying processes such as sepsis, pneumonia, trauma, multiple transfusions, and pancreatitis. ARDS is defined by (1) acute onset, (2) bilateral infiltrates in chest x-rays, (3) absence of left ventricular failure, and (4) severe arterial hypoxemia with a PaO2/FiO2 ratio less than 200 mmHg. Still, ARDS is feared (mortality 30-40%) and relatively frequent (incidence between 13.5 per 100,000 to 75 per 100,000). Acute lung injury (ALI) describes a similar, but less severe, clinical condition, with PaO2/FiO2 values between 200 and 300 mmHg. Despite ongoing and intensive scientific research in this area, the mechanisms underlying ALI/ARDS are still not completely understood, and until recently, there were no studies demonstrating any beneficial effect of a single treatment modality in ARDS. The recent report that a specific approach to ventilatory support can significantly reduce mortality in ARDS underscores the need for better understanding of the pathophysiological events occurring in this syndrome. This review therefore summarizes the current pathophysiological concepts underlying the evolution of acute hypoxemic respiratory failure and focuses on: (1) possible reasons for the development of ALI/ARDS; (2) cellular and humoral mediator responses leading to a sustained and self-perpetuating inflammation of the lung; (3) consequences with regard to fluid balance, pulmonary perfusion, ventilation, and efficiency of gas exchange; and (4) mechanisms underlying the aggravating complications commonly seen in ARDS, especially ventilator-associated lung injury, ventilator-associated pneumonia, and lung fibrosis.

Intercurrent illness and episodes of hospitalization and surgery are common in an aging population, who, at the same time, are experiencing age-related bone loss. The objective was to test the hypotheses (1) that intercurrent illness severe enough to require hospitalization produces clinically important bone loss, and (2) that antiresorptive therapy will reduce that loss. The study was a retrospective analysis of bone mineral density (BMD) change at hip and spine in subjects of the risedronate postmenopausal osteoporosis phase III trials experiencing serious adverse events (SAEs). Subjects were 243 hospitalized for non-skin cancers, pneumonia, myocardial infarction, cerebrovascular accident, gallbladder disease, and pancreatitis, on whom BMD data were available both before and after the SAE; and 286 non-hospitalized control subjects matched to those with SAEs by age, height, weight, prevalent fracture, and visit interval. In hospitalized, placebo-treated participants, the annualized percent change in BMD (mean+/-SEM) across the period of hospitalization was -0.65+/-0.39 at lumbar spine, -1.13+/-0.55 at femoral neck, and -2.66+/-0.58 at femoral trochanter; the corresponding values for the non-hospitalized, placebo controls were +0.46+/-0.28, -0.77+/-0.34, and -0.67+/-0.34. These values were more negative at all three sites for the hospitalized subjects, and significantly so at lumbar spine and femoral trochanter (P=0.019 and 0.002, respectively). By contrast, in the risedronate-treated participants, all sites exhibited bone gain and there was no significant difference between hospitalized and non-hospitalized participants. Intercurrent illness resulting in hospitalization produced a rapid bone loss across the period of illness comparable in magnitude to documented age-related loss. Risedronate in a dose of 5 mg/day effectively abolished this loss.

After inconspicuous pregnancy and birth, a 16-year-old mother presented her male baby 5 days later with severe diarrhoea and vomiting. During the following weeks, the child temporarily showed hypotension, hypothermia and increased body temperature, bradyarrythmia with apnoea, continuing diarrhoea, sometimes vomiting and developed signs of pancreatic insufficiency. Due to increasing loss of weight and obviously severe dystrophia, parenteral nutrition had to be initiated. All clinical investigations revealed no underlying disease. Numerous biopsies, mainly from the gastrointestinal tract were taken, but no relevant pathological findings were disclosed. The baby was found lifeless by his mother, 4 months after birth. According to the death certificate, the physicians regarded the lethal outcome as a case of sudden infant death syndrome (SIDS). Histological and immunohistochemical investigations of organ samples revealed signs of myocarditis, pancreatitis and focal pneumonia. Molecularpathological techniques were used to detect enterovirus RNA from tissue samples from the myocardium, liver and pancreas. Enteroviral myocarditis with concomitant pancreatitis was determined as cause of death.

Streptococcus pneumoniae ( S. pneumoniae ) has been associated with hemolytic uremic syndrome (HUS), which is an unusual but serious disease in childhood. We conducted a retrospective review of children aged less than 18 years with S. pneumoniae -associated HUS in northern Taiwan from January 2000 to June 2005. The demographic characters, clinical courses, and outcomes were analyzed. Seven children (three girls, four boys) with S. pneumoniae -associated HUS were studied. The median age at onset of HUS was 40 months (range: 25-60 months). The median duration of hospital stay was 36 days (range: 15-50 days). The interval between the onset of illness attributable to S. pneumoniae and the development of HUS was around 1-2 weeks. The onset of oliguria developed within 2 weeks after illness. Six patients required dialysis with median duration of 16 days. Three patients had leukopenia as the initial presentation. All seven patients had pneumococcal pneumonia complicating with empyema, and two of them received decortication via video-assisted thoracoscopic surgery. Between patients who needed dialysis or not, there was no significant difference in age, sex, duration of thrombocytopenia, incidence of extra-renal complications, such as hepatitis, pancreatitis, and hypertension, and length of hospital stay. The seven patients survived with normal renal function. HUS is a potentially fatal complication of S. pneumoniae infection. Clinicians managing patients with pneumococcal pneumonia with empyema accompanied by leukopenia should beware of the development of HUS. The long-term prognosis for recovery of renal function appears to be good in these patients in northern Taiwan.

Extra-corporeal life support (ECLS) has been applied successfully to congenital respiratory defects but less optimally to acquired pulmonary failure. We extended this support to certain extreme complexities of patients with acute respiratory distress. From January 2003 to June 2005, 16 (nine men and seven women) patients refractory to ventilator support were treated with ECLS. Their median age was 32.4 years (1.5-70). The triggering events were pulmonary haemorrhage (n = 4), pneumonia (n = 7), aspiration (n = 2) and pancreatitis (n = 3). The indications for support were hypoxaemia in 13 and hypercapnia in three patients. Ten (63%) met the criteria of fast entry. Thirteen (81%) received veno-venous (V-V) mode support and the other three received veno-arterial mode support initially, but then converted to V-V mode after sufficient oxygenation stabilised haemodynamics. Initial pump flow was maximised to improve (mean 3250 +/- 1615 ml/min) to improve the oxygenation. Four patients with active pulmonary haemorrhage were heparin free in the first 12-24 h of support without complications. Excluding one prematurely terminated patient because of brain permanent damage, the duration of support was 162 +/- 95 h (67-363). Eleven (69%) weaned successfully from ECLS and 10 (63%) discharged and regained normal pulmonary performance in a median of 26.8 months follow-up. Pulmonary support using ECLS was feasible in selected patients with acute respiratory distress. Modification of guidelines for liberal use, early deployment before secondary organ damage and prevention of complications during support were the key to final success.
